Most solar kits have a dirty little secret they don't tell you about:
They waste valuable power.
Here's the deal
12V solar panels actually output around 20V
12V leisure batteries charge at just over 12V*
Standard PWM controllers simply drop those extra 8V — throwing away precious power
In cloudy Britain where every watt counts, this is a problem.
The Voltanic Difference
Every Voltanic Kit takes those wasted volts and converts them into extra amps using Advanced MPPT (Maximum Power Point Tracking) Technology.
Harvest 100% of your Solar Energy - No wasted watts
Charge your Batteries 30% Faster
More Power, Fewer Panels - Perfect for tight spaces
Better Value Investment - Get what you pay for
Maximum Power. Zero Waste.
Real World Comparison:
100W Panel Performance
Watts = Volts x Amps
| Controller | Standard PWM | Voltanic MPPT |
|---|---|---|
| Panel Voltage | 20V | 20V |
| Controller Charging Voltage | 12V (PWM reduces voltage) | 12V (MPPT reduces voltage) |
| Amperage | 5.8A (amps stays same) | 8.2A (MPPT increases amps) |
| Power Output | 12V × 5.8A = 70W | 12V × 8.2A = 98W |
| Power Wastage | ~30W (lost as heat) | ~2W (conversion loss) |
PERC Cell Technology: Everything You Need to Know
What is PERC Technology?
First, let’s talk about PERC. PERC stands for Passivated Emitter and Rear Cell, and it’s a type of solar cell technology that has become increasingly popular in recent years. PERC cells have a layer of passivation on the rear surface, which helps to reduce electron recombination and boost the efficiency of the cell. This means that PERC cells are more efficient at converting sunlight into electricity than traditional cells.
Standard Module
Some light is absorbed by the panel while other pass or reflect.
Mono PERC Module
A passivated layer is added on the rear side of the module so as to reflect the light passed.
What is Monocrystalline Technology?
Benefits of PERC and Monocrystalline Technology
Solar panels that feature both PERC and monocrystalline technologies have several benefits, including:
+ Increased Energy Production: PERC technology helps to boost the efficiency of solar cells, while monocrystalline technology is known for its high efficiency. By combining the two, manufacturers can produce panels that are even more efficient at converting sunlight into electricity, up to 5% more.
+ Greater Reliability: Solar panels that feature both PERC and monocrystalline technologies are also known for their reliability. This means that they can continue to generate electricity even under challenging weather conditions.
+ Same manufacturing costs: The cost efficiency of producing PERC panels at the same cost as conventional panels has contributed significantly to their growing popularity and anticipated market expansion. Consequently, consumers can now obtain a superior quality product at an affordable price, making PERC panels an attractive option for those seeking a better deal.
